Vedclass · Answer

(B) In a $PN$ junction diode,when the $P$-region is connected to the negative terminal and the $N$-region is connected to the positive terminal of an external battery,the diode is said to be in reverse bias.In this state,the external electric field is in the same direction as the internal electric field of the depletion region.This causes the majority charge carriers to move away from the junction,which increases the width of the depletion layer.As the width of the depletion layer increases,the potential barrier also increases,making it more difficult for charge carriers to cross the junction.
